Implantable defibrillators after infarction and management of type 2 myocardial infarction
THE CONTEXT
The opening statement continues the discussion of implantable defibrillators. The target then distinguishes the management priorities of type 2 myocardial infarction.
Prevention of sudden cardiac death
•
Implantable defibrillators help prevent sudden cardiac death after myocardial infarction in patients with severe left ventricular impairment, defined here as an ejection fraction ≤ 30%.
Type 2 myocardial infarction
•
Optimal management and treatment remain unestablished, and there is no evidence that treatments for type 1 myocardial infarction are effective in type 2 myocardial infarction.
•
Treatment should focus on the underlying cause of presentation and, where applicable, previously undiagnosed concomitant coronary artery disease.
